<p>The <code>signalfx</code> adapter collects Istio metrics and trace spans and sends them
to <a href="https://signalfx.com">SignalFx</a>.</p>

<p>This adapter supports the <a href="https://istio.io/docs/reference/config/policy-and-telemetry/templates/metric/">metric template</a>
and the <a href="https://istio.io/docs/reference/config/policy-and-telemetry/templates/tracespan/">tracespan template</a>.</p>

<p>If sending trace spans, this adapter can make use of certain conventions in
the tracespan format that is configured to send to this adapter.  Here is an
example tracespan spec that will work well:</p>

<pre><code class="language-yaml">apiVersion: config.istio.io/v1alpha2
kind: instance
metadata:
  name: signalfx
spec:
  compiledTemplate: tracespan
  params:
    traceId: request.headers[&quot;x-b3-traceid&quot;] | &quot;&quot;
    spanId: request.headers[&quot;x-b3-spanid&quot;] | &quot;&quot;
    parentSpanId: request.headers[&quot;x-b3-parentspanid&quot;] | &quot;&quot;
    # If the path contains query parameters, they will be split off and put into
    # tags such that the span name sent to SignalFx will consist only of the path
    # itself.
    spanName: request.path | &quot;/&quot;
    startTime: request.time
    endTime: response.time
    # If this is &gt;=500, the span will get an 'error' tag
    httpStatusCode: response.code | 0
    clientSpan: context.reporter.kind == &quot;outbound&quot;
    # Span tags below that do not have comments are useful but optional and will
    # be passed to SignalFx unmodified. The tags that have comments are interpreted
    # in a special manner, but are still optional.
    spanTags:
      # This is used to determine whether the span pertains to the client or
      # server side of the request.
      context.reporter.local: context.reporter.local
      # This gets put into the remoteEndpoint.ipv4 field
      destination.ip: destination.ip | ip(&quot;0.0.0.0&quot;)
      # This gets flattened out to individual tags of the form
      # 'destination.labels.&lt;key&gt;: &lt;value&gt;'.
      destination.labels: destination.labels
      # This gets put into the remoteEndpoint.name field
      destination.name: destination.name | &quot;unknown&quot;
      destination.namespace: destination.namespace | &quot;unknown&quot;
      request.host: request.host | &quot;&quot;
      request.method: request.method | &quot;&quot;
      request.path: request.path | &quot;&quot;
      request.size: request.size | 0
      request.useragent: request.useragent | &quot;&quot;
      response.size: response.size | 0
      # This gets put into the localEndpoint.name field
      source.name: source.name | &quot;unknown&quot;
      # This gets put into the localEndpoint.ipv4 field
      source.ip: source.ip | ip(&quot;0.0.0.0&quot;)
      source.namespace: source.namespace | &quot;unknown&quot;
      # This gets flattened out to individual tags of the form
      # 'source.labels.&lt;key&gt;: &lt;value&gt;'.
      source.labels: source.labels
      source.version: source.labels[&quot;version&quot;] | &quot;unknown&quot;
